Categories exist in order to help people find other pages on the same topic. When people are looking for e.g. "voice actors", they are looking for all people of that occupation, not just male or female actors/actresses. The male/female distinction actively hinders that goal, and on top, is only applicable to a few nouns which can even express this nuance.

You being polite to the women in the same profession is cute, but misplaced in this case.
